final class TFree extends ConcreteTyp

A free type variable (ML constructor TFree). name is the name of the type variable (e.g., "'a'") and sort its sort. (The sort is a list of fully qualified type class names.) Note that type variables whose names do not start with ' are not legal in Isabelle.

    Equality of types.

    Equality of types. Returns true iff the two Typ instances represent the same type in the Isabelle process. (E.g., a Ctyp and a TFree can be equal.) May throw an exception if the computation of the terms fails. (But will not fail if await or a related FutureValue method has returned successfully on both terms.)

    Waits till the computation of this value (in the Isabelle process) has finished. (Or until an exception is thrown.)

    returns

    this value, but it is guaranteed to have completed the computation

  14. def forceFuture(implicit ec: ExecutionContext): Future[TFree.this.type]

    A future containing this object with the computation completed.

    A future containing this object with the computation completed. In particular, if this value throws an exception upon computation, the future holds that exception.

    Roughly the same as Future { this.force }.

  20. lazy val mlValue: MLValue[Typ]

    Transforms this type into an MLValue containing this type.

    Transforms this type into an MLValue containing this type. This causes transfer of the type to Isabelle only the first time it is accessed (and not at all if the type came from the Isabelle process in the first place).

    Produces a string representation of this object. Uses the Isabelle pretty printer.

    ctxt

    The Isabelle proof context to use (this contains syntax declarations etc.)

    symbols

    Instance of Symbols for converting to Unicode. Default: global default instance Symbols.globalInstance. Use prettyRaw to avoid conversion to Unicode.

    Produces a string representation of this object. Uses the Isabelle pretty printer. Does not convert to Unicode, i.e., the return value will contain substrings such as \<forall>)

  27. def someFuture: Future[Any]

    Returns a future that completes when the computation of this object is complete.

    Returns a future that completes when the computation of this object is complete. (Or that holds an exception if that computation throws an exception.) However, upon successful completion, the future may return an arbitrary (and thus useless) value. May be faster to implement than forceFuture because there may be already a future available but that returns the wrong value.

    A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.

    This can be useful to constructing human readable messages about this value.

  31. def toString: String

    Produces a string representation of this type.

    Produces a string representation of this type.

    This is not a "pretty" representation, it does not use Isabelle syntax, and subterms that are stored only in the Isabelle process are replaced with a placeholder (thus this method does not invoke any potentially communication with the Isabelle process).
